20 Jun 2016 --- Acid whey is a valuable raw material that can be used to create high quality and nutritious consumer products, according to Torben Jensen, Category & Application Manager for Fresh Dairy Products at Arla Foods Ingredients. Whey is a traditional byproduct that comes from the production of various dairy products, including cheese. However, in recent years, whey has emerged as a high value product in its own right, particularly now that the protein trend is so strong. This means that whey, as a high quality dairy protein, also has a sustainability advantage from a marketing perspective.
